I don't know any free ones that actually are GOOD and reliable, but for what it worth, I bought Blackberry Video Converter by Nidesoft. This program is amazing, as I converted several movies and not a glitch or audio sync problem at all. You can make the quality in almost any way possible.
/edit: They also have the video converter that I bought and although I haven't tested out every possible combo, this program works wonders and THIS is what you might be looking for. Again its not free, and its not expensive either and it WORKS AWESOME!
